Clash of Claims: The Philippines, Vietnam, and Taiwan’s Legal Battle Over the South China Sea

By Louis ‘Barok‘ C. Biraogo

In the vast expanse of the South China Sea, a new chapter in the age-old maritime dispute unfolds, casting a shadow over regional stability and raising the stakes for international diplomacy. The latest twist in this enduring saga comes as Taiwan’s Ministry of Foreign Affairs (MOFA) forcefully rejects the claims made by the Philippines and Vietnam for an extended continental shelf, deeming them “unacceptable” and an infringement upon Taiwan’s sovereignty and rights. This rejection, cloaked in the language of international law and sovereign rights, adds another layer of complexity to an already convoluted dispute, threatening to escalate tensions in one of the world’s most contested maritime regions.

Echoes of Empire: Taiwan’s Historical Ties to the South China Sea

To understand the current impasse, one must delve into the historical roots of Taiwan’s claims in the South China Sea. Taiwan, formally known as the Republic of China (ROC), has long asserted its sovereignty over several islands and features in the South China Sea, including the Spratly Islands (Nansha Islands), the Paracel Islands (Xisha Islands), and the Pratas Islands (Dongsha Islands). These claims date back to the early 20th century when the ROC government, then based in mainland China, issued maps marking these territories as part of its domain.

Following the Chinese Civil War, the ROC government retreated to Taiwan in 1949, but it retained its maritime claims. These assertions have been consistently reaffirmed, including in 1993 when Taiwan issued its Law on the Territorial Sea and the Contiguous Zone, and in 1999 with the promulgation of the Law on the Exclusive Economic Zone and the Continental Shelf. Taiwan’s stance is further bolstered by its occupation of Taiping Island (Itu Aba), the largest naturally occurring feature in the Spratlys, which it has administered since 1956.

Uncertain Waters: Scrutinizing Taiwan’s South China Sea Claims

Opponents of Taiwan’s claims, including the Philippines and Vietnam, present a multi-faceted rebuttal grounded in international law and historical evidence. At the heart of their argument is the 1982 United Nations Convention on the Law of the Sea (UNCLOS), which sets the framework for maritime entitlements and the resolution of disputes.

1. UNCLOS Provisions: UNCLOS stipulates that coastal states have sovereign rights over their Exclusive Economic Zones (EEZ) extending 200 nautical miles from their baselines. Beyond this, a state can claim an extended continental shelf if it meets specific geological criteria. The Philippines and Vietnam argue that their continental shelves naturally extend beyond 200 nautical miles, thus entitling them to additional maritime zones.

2. The 2016 Arbitral Tribunal Ruling: In 2013, the Philippines brought a case against China to the Permanent Court of Arbitration in The Hague under UNCLOS. The tribunal’s landmark 2016 ruling invalidated China’s extensive “nine-dash line” claims in the South China Sea and clarified that certain maritime features, including those claimed by Taiwan, do not generate EEZs or continental shelves. Although Taiwan was not a party to the case, the ruling indirectly affects its claims, as it reinforces the primacy of maritime entitlements based on UNCLOS.

3. Historical Evidence: Critics argue that Taiwan’s historical claims lack a solid foundation in contemporary international law. They contend that historical usage and administration do not confer sovereign rights under UNCLOS, which prioritizes geological and legal criteria over historical assertions.

A Legacy of Connection: Historical Foundations for Taiwan’s Claims

Taiwan’s defense of its claims is equally robust, invoking both historical sovereignty and legal principles.

1. Historical Sovereignty: Taiwan maintains that its historical administration and occupation of key islands in the South China Sea predate the claims of other states. The continuous presence and administration of Taiping Island and other features are cited as evidence of its longstanding sovereignty.

2. Legal Rights under UNCLOS: Taiwan argues that, as a coastal state, it possesses inherent rights to an EEZ and continental shelf as defined by UNCLOS. Despite not being a signatory to UNCLOS, Taiwan adheres to its principles and asserts that its continental shelf extends beyond 200 nautical miles, qualifying it for extended maritime zones.

3. Equitable Solutions: Taiwan emphasizes its willingness to engage in “equal consultation” with other claimants to address disputes. This approach aligns with the UNCLOS mandate for peaceful resolution of conflicts and cooperative management of shared resources.

Beyond Words: Analyzing the Effectiveness of Taiwan’s Counterclaims

Taiwan’s opposition to the claims of the Philippines and Vietnam rests on a combination of historical assertion and contemporary legal interpretation. However, its position is complicated by several factors:

1. Limited International Recognition: Taiwan’s diplomatic isolation and lack of recognition as a sovereign state by the United Nations undermine its ability to leverage international legal mechanisms effectively.

2. The 2016 Arbitral Tribunal Ruling: While Taiwan rejects the tribunal’s jurisdiction over its claims, the ruling’s implications cannot be ignored. It sets a precedent that challenges the validity of Taiwan’s assertions based on historical occupation.

3. Regional Dynamics: The South China Sea dispute involves multiple claimants with overlapping interests, creating a volatile environment where bilateral and multilateral negotiations are fraught with challenges.

Recommendations

For Taiwan:

Engage in Multilateral Dialogue: Taiwan should proactively participate in regional forums and engage with other claimants to find mutually acceptable solutions.
Adopt Confidence-Building Measures: Enhancing transparency and reducing military activities in disputed areas can help de-escalate tensions.
Strengthen Legal Frameworks: Taiwan should align its maritime claims more closely with UNCLOS provisions to bolster its legal standing.

For the Philippines and Vietnam:

Pursue Legal Avenues: Continue to seek international legal recognition of their claims through UNCLOS mechanisms and other international bodies.
Foster Regional Cooperation: Collaborate with other ASEAN nations to present a unified front and promote peaceful resolution of disputes.
Promote Sustainable Development: Focus on joint development of resources in disputed areas to benefit all parties involved.

In the convoluted world of the South China Sea dispute, the interplay of historical claims, legal principles, and geopolitical maneuvering creates a high-stakes drama. As tensions simmer, the path to resolution lies not in unilateral assertions but in the arduous journey of diplomacy, dialogue, and adherence to international law. The world watches with bated breath, hoping for a peaceful denouement to this enduring conflict.
